SPECIFICATION forming part of Letters Patent No. 637,135, dated November14, 1899.

Application iiled March 30, 1899. Serial No. 711,140. (No model.)

T0 all whom, it may concern:

Be it known that I, GEORGE E. LASH, a citizen of the United States,residing at Elkhart, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Improvements in Rotary Motors; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to motors which are designed to be run bywater-power for operating display devices in store-windows and actuatinglight machinery-such as sewingmachines, churns, scroll-saws, iiy-fans,and the like. agent, it will be understood that any of the usualmediums-'steam or compressed airmay be used.

lSimplicity of construction, combined with efficiency, durability,lightness, economy, and ease of operation are some of the many endssought to be attained in devising the invention, which consists,essentially, of the novel features, details of construction, andcombinations of the parts which hereinafter will be more fullydescribed, illustrated, and claimed.

In the drawings, Figure 1 is a central longitudinal section of a motorconstructed in accordance with this invention for attaining the endsthereof. Fig. 2 is a detail plan section. Fig. 3 is a view in elevationof a bearing. Fig. 4 is a section on the line a: .fr of Fig. 3. Fig. 5is a detail perspective view of a portion of the motor-wheel. Fig. 6 isa detail View of a bucket-blank. Fig- '7 is a detail section of thejet-nozzle.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The motor-wheel l is composed of a rim portion, spokes 2, and a shaft 3and operates within a casing composed of a lower portion 4 and a coveror upper portion 5. This casing is preferably constructed of sheetmetal, although any suitable material may be employed in the formationthereof. The outer portion of the cover 5 curves on the arc of a circleconforming to the periphery of the mo- While water is the principalmotive tor-wheel, so as to economize in space. The cover is formed withan outer flange 6, which overlaps the sides of the body 4, and with apendent fiange 7 to enter the upper portion of the body and prevent thesplashing of the water upon the floor, ledge, or other support uponwhich the motor may be placed. An outlet 8, consisting of a short lengthof tube, is applied to an end of the body 4, and a hosepipe is adaptedto be coupled thereto for conveying the spent water to the requiredpoint of discharge. Y

A nozzle 9 is applied to the peripheral portion of the cover 5 to oneside of a vertical line and has a tangential arrangement, so as to causethe jet of water or other motive agent to impact against the buckets ofthe motorwheel and drive the latter, so as to utilize a maximum amountof the force or head of the jet. It has been found desirable to have thenozzle 9 adjust-able, so as to vary its tangential relation to cause thejet to impact against the buckets of the motor-wheel at any pointbetween their inner and outer edges. rIhis adjustment of the nozzle isalso beneficial, since it allows for variations of workmanship in theassembling of the parts, whereby the jet may be given any requiredinclination with reference to the motor-wheel; As shown, the curved orperipheral portion of the cover is formed with a semicircular portion10, which projects outwardly therefrom 'and which has an elongatedopening 11 formed therein through which the nozzle 9 passes. Asemicircular iiange or stop 12 is applied to the inner portion of thenozzle and obtains a bearing against the inner face of the part 10 andprevents outward movement of the nozzle. A washer 13 is slipped upon theouter portion of the nozzle and is plano-concave, the concave sidecorresponding to the convexity of the part lO, so as to secure a snugfit thereagainst, and the plane surface forming a seat for the nut 14 toobtain a bearing against, said nut being mounted upon a threaded portionof the nozzle and adapted to clamp the part 1Q between the washer 13 andthe flange or stop 12. Upon loosening the nut 14 the nozzle can beturned to vary its inclination and when properly positioned IOO issecured by retightening the nut. The washer 13 and fiange 12 are of such-relative lengths with reference to the opening 1l as to cover thelatter at all adjustments of the nozzle within the range of itsmovements. The hose-pipe for conveying the water or other motive agentto themotor is adapted to be co-upled to the projecting end of thenozzle 9 in any of the usual ways.

Two-part journal-boxes are applied to the sides of the body 4 andreceive the shaft 3. These boxes are fitted into notches or cutawayportions in the upper edges of the sides of the body and have their edgeportions grooved or channeled, so as to receive the marginal portions ofthe body bordering upon the notches or openings into which the boxes arefitted. The lower bearing 15 is grooved or channeled at its bottom andside edges, and the upper bearing 1G is grooved at its sides only and isformed in its outer face with a longitudinal seat 17 to receive a key18, by means of which the boxes are secured when in place. The edges ofthe key-seat 17 are undercut or inwardly beveled, so as to overlap thebeveled edges of the key 18 and retain the latterin place. This key 18is slightly longer than the width of the box, so that its projectingends will come beneath the outer roll or fiange 19 of the body 4 andsecure the box against accidental displacement. An endwise movement ofthe key will unseat it and permit the upper bearing 16 of each of theboxes to be removed when it is required to disengage the motor-wheelfrom its casing` for any purpose. The shaft 3 is prevented from endwiseplay by shoulders or collars 20, applied to or formed therewith andengaging withv the inner sides of the boxes. Corresponding shoulders orcollars 21 are applied to the shaft and engage with the outer sides ofthe bearings, and the latter, being held between inner and outershoulders and in turn being secured to the sides of the casing, serve tostrengthen and brace the latter.

The rim portion of the motor-wheel is composed of a band and side rings23, the latter being joined at their inner edges to the outer edges ofthe band 22 and forming aspace to receive audconline the jet of water inthe operation of the motor. The buckets 24 subdivide the peripheralspaceinclosed between the band 22 and rings 23 and receive the impact ofthe water or other motive agent. These buckets extend square across thespace, so as to receive the full force of the jet, and curve betweentheir inner and outer edges, the curve being greatest on a medial line.The inner portions of the buckets are disposed, approximately, uponradial lines and the outer edge portions have a tangential disposition,thereby giving to the buckets a form which pockets the water impactingthereagainst, whereby the weight of such water is utilized in additionto the momentum for effective work in propelling the Wheel when themotor is in operation. The construction ofthe buckets is such that whenthe water reaches the lowest position it will discharge without impedingthe forward rotation of the motorwheel. The buckets touch the band 22 attheir inner edges and the rings 23 at their sides and may be secured tothese parts in any desired manner. In the preferable construction thebuckets are formed from blanks struck from sheet metal of suicientstiness and having a series of ears or tongues 25 along their edges topass through openings 26, formed in the rings 28 in coincident relationwith the ears 25, so as to receive the latter,l

said ears or tongues being bent after their passage through theopeningsy26, so as to hold the parts in fixed relation. The blanks arecurved between their inner and outer edges prior to their assembling.This construction admits of any bucket being removed and easily replacedwhen crippled or unfitted for further service.

The motor is light in weight and can be driven by a small water-pressurefor operating, advertising, or displaying devices in store-windows andother places and can be utilized for operating light machinery gener-lally, and when constructed for any particular purpose it is to beunderstood that various changes in the form, proportions, and minordetails of construction may be resorted to without departing from thenature or sacriiicing any of the advantages of the invention.

Having thus described the invention, what is claimed as new is- 1. In amotor of the character described, the combination with a motor-wheel,and a casing therefor having a deflected or curved portion, of a nozzlepassing through an opening formed in the deflected portion of the casingand adapted to be moved to any desired position with reference to a linedrawn tangentially7 to the motor-wheel, and means applied to the nozzleand arranged to come upon opposite sides of the deflected portion of thecasing to clamp it and secure the nozzle in an adjusted position,substantially as set forth.

2. In a motor of the character described, the combination with themotor-wheel, and a casing therefor having a deflected or curved offsetportion, of a nozzle passing through an opening in the said curved oisetportion and having a curved iiange or stop to engage with the inner sideof the said offset, a plano-concave washer slipped upon the nozzle andengaging with the outer surface of the aforementioned offset, and aclamp-nut mounted upon the nozzle for securing it in an adjustedposition, substantially as specified.
